Referring in detail to the construction of my` invention as a means ofresurfacing and widening road structures, lj provide in connection withthe road bed tof integrally massed hard materials side plates 2 and 3shown in Fig. l, as side supports for extended portion of a roadresurfacing material where it is desired to widen the road whileresurfacing the same.

The side plate-s 2 and :i are provided with integral upturned outerflanges t and 5 for holding the resurfacing materials substantially inplace, while the lower and inner flanges i5 and'l of the plates and 3are adapted to flank and engage `the outer vertical edges of the roadbed i, which affords a continuous massive foundation for the newsurface. It are connected by suitably spaced tierods`8 which `extendacross the road bed i to establish a tensile connection between thesetwo plates.

The tie rods t may bessubstantially secured to the Aplates E and 3either by riveting, welding, r

9. This cushioning course `Ei serves the twofold The inner edges of theplates 2 and purpose of providing a leveling agent for leveling i up theinequalities of the pavement and providing a proper foundation for thebrick course on top.

. The plates 2 and 3 may be provided with transf It will be noted thatthe side plates I2 and I3 in Fig. 2 are similar to the plates 2 and 3shown in Fig. 1, excepting the reinforcing bracket or angle braces I4and I5 for providing a compression bearing for supporting the plates i2and i3 against the sides of the road bed I. These plates are preferablyconnected substantially together across the road bed i by tie rods 8similar to the arrangement shown in Fig. 1.

It will be observed thatin the eventl of Aoutward strains or stressesupon the saddling or side plates of my invention they will be amplysupported through the tensile strengthof the .tie rods 3. For instance,the tie rods 8 as observed in Fig. l carry a tensile strain when roadstresses and strains are exerted against `the plates 2 and 3. The tierods 8 cannot give Y Inaterially' Lin `their support of these stressesand they are aided by the inward gripping or clamping action of Yflanges6 and I against the massive side walls of the road bed I. rIhisarrangementprovides a very strong cantilever construction ontheprinciple of a third class Vleverage wherein therods provide the tensilefpower; the outward and downward stress 0n the plates 2 and 3 theweight; and;.the flanges G and 'I the fulcrum.

The side plates in Fig. 3 are similar to those shown in Fig. 1 with theexception that these plates extend beyond the upturned curb or iiangewith the idea of securing additional support from a wider range coverageof sub-grade along the road shoulder. These flanges are numbered i6 andI'I in the drawing.

Where it is desirable to widen a road structure and where it isnecessary to resurface the original structure, Fig. 4 illustrates amethod of providing metallic supporting side plates it and I9. Theseside plates I8 and i9 are depressed so that the top of the upturnedflanges 2G and El are level with the surface 2t of the original roadstructure. The top portion of these plates resemble a chan nel and thespaces between the flanges Sii and 22 and 2I and 23 are lled with somesuitable surface material such as bricks 25 and asphaltic or bituminousmixtures It will be noted that in this manner the surface of the widenedportionl of the road Vwill then be level with the surface 24 or theoriginal road structure, thus providing a level trafic surface over theentire expanse of completed road. It will also be noted in Fig. e thattie rods are employed to join together the two outside plates iS and I9,while they are further braced on the bottom side respectively by bracesor brackets 2l' and 2S which have an inward gripping or clamping actionagainst the sides of the original road structure. The principle ofsupport used here is the same as explained above in connection with Fig.1.

There are many thousands of miles of roads originally built of concreteand other materials which have begun to crack and disintegrate to suchan extent that it is necessary to resurface them in order to save themor prolong their life. When materials such as paving brick, blocks,bituminous or asphaltic mixtures are used, itis necessary to have aretaining wall or curb to hold such surfacing material in place. It isfrequently found desirable to widen these old road structures. In suchan event it is necessary to provide an `adequate foundation or base forsuch surfacing material. My invention adequately meets both of theseneeds by means of a rplurality of forms of steel plates which functionas follows:

The plates are placed along both outer edges of the road with one edgeof the plate resting on the edge of the old road structure. The platesthen extend on a plane outwardly and away from the edge of the road forthe desired distance and have an upturned flange which acts as aretaining curb for the surfacing material. On the bottom side of theplates and extending down adjacent to and in contact with the outer edgeof the old road structure are turned down flanges 6 and l. The plates onopposite sides of the road are then firmly joined together across theexisting road bed by means of spaced tie rods 8 so that there can be notendency for the plates to spread.

This construction also takes advantage of the tensile strength providedby the tie rods 8 acting against the gripping or clamping action uponthe sides of the road structure by the above mentioned downturnedflanges, so that in the event of excessive weight occurring on the outeredge of the said plates it would be immediately checked by the abovementioned forces. Additional rigidity may be given to these plates toprevent bending or sagging by means of brackets at spaced intervals, asshown in the accompanying drawmg.

After having placed these plates, tie rods and braces'in place it is avery simple matter to cover the whole road widening and resurfacingsupport structure with a satisfactory surfacing ma terial which will addmany years to the life of the old road structure. The manner of usingthe metallic plates permits much easier installation and it is cheaperthan constructing this extra width base and curb of concrete or othersimilar material, and eliminates the necessity of tying the road up fortraffic while the concrete is curing.

In the event it is desired to simply widen Ia road (see Figs. -i and 6)and not resurface the old part, my invention provides for the plates vtobe formed so that they will be depressed on either side of the old roadstructure in such a manner that when the plates are surfaced with asuitable surfacing course, they will present an even and level wearingsurface hush with the original pavement. In this event it will be foundnecessary to have these plate units hrmly joined together by at or roundtie rods across the top of the old pavement, and it may b e desirable torabbet a slot or groove across the old pavement in which these tie rodswould rest so that it would not form a ridge or raised place in the oldroad portion. This method is clearly set forth in the accompanyingdrawing in the iigures above mentioned.

Where it is desired to provide side plates for a new road structure as ameans of strengthening the road support and holding the same with asubstantial inward grip along the sides of the base to prevent ktheshoulders of the road bed from more easily cracking, chipping andotherwise distintegrating under stresses and strains of traiic overweakened or uneven sub-grades, `the side plates 29 shown in Fig. ll willamply meet such a need, and is held in place by tie rods 3B and 3|embedded in the pavement i as they extend across through the road bed toconnect opposite side platesl at a point intermediate their outer topedges and their inner and lower edges.

It will be noted that the basic idea of the present Vinvention residesin the provision of shelf-like structures which in turn derive theirmain support from the foundations of the old road structure. This methodof widening a road obviates the necessity of providing anew vfoundationstructure for the road extension and at the same time firmly andruggedly co-ordinates the new surface structure with the old foundation.'Ihis results in a new road surfacewhich is supported in part directlyupon the old foundations and in part upon the shelf-like extensionplates, although the new surfacing gives the appearance of a completelynew road throughout.

The invention is one which utilizes to the fullest extent the value ofthe original road foundations, which though they may be impaired `on thesurface are nevertheless suficiently massive and rugged to support thenew and extended surfacing. This method of mending roads results in agreat saving of materials` and time and expense, and at the sametimeresults in a road of increased surface depth and of materiallygreater width than heretofore.

Numerous Variations in the method of utilizing the present invention arecontemplated, depending more or less upon local conditions and thecharacter of the original road which it is desired to resurface.
